| Subject: drm/vmwgfx: Fix Ubuntu 17.10 Wayland black screen issue |
| |
| From: Sinclair Yeh <syeh@vmware.com> |
| |
| commit cef75036c40408ba3bc308bcb00a3d440da713fc upstream. |
| |
| This is an extension of Commit 7c20d213dd3c ("drm/vmwgfx: Work |
| around mode set failure in 2D VMs") |
| |
| With Wayland desktop and atomic mode set, during the mode setting |
| process there is a moment when two framebuffer sized surfaces |
| are being pinned. This was not an issue with Xorg. |
| |
| Since this only happens during a mode change, there should be no |
| performance impact by increasing allowable mem_size. |
